Based on the data from the China Family Panel Studies (CFPS) in 2018, the relationship between internet use and informal workers' wages and its internal mechanism were empirically discussed using the ordinary least squares and endogenous switching regression(ESR) model. The study found that internet use could significantly raise the level of wages of informal workers, and this conclusion still holds after the endogenous problem was solved through the endogenous switching regression model. Further research found that the influences of the internet use on informal workers' wages was heterogeneous. In other words, internet use has a more obvious impact on the wages of informal workers aged 31 to 40, 41 to 50, and 51 to 60 with the educational level of university and above in cities and towns, while it has a significant negative impact on wages of informal workers aged 16 to 20.
基于中国家庭追踪调查(CFPS)2018 年的数据,利用普通最小二乘法和内生转换回归(ESR)模型,实证讨论了互联网使用与非正规工人工资之间的关系及其内在机制。研究发现,互联网的使用可以显著提高非正规工人的工资水平,而且这一结论在通过内生转换回归模型解决内生性问题后仍然成立。进一步的研究发现,互联网的使用对非正规工人工资的影响存在异质性。也就是说,互联网的使用对年龄在 31 至 40 岁、41 至 50 岁和 51 至 60 岁、城镇地区具有大学及以上学历的非正规工人的工资有更明显的影响,而对年龄在 16 至 20 岁的非正规工人的工资有显著的负面影响。
